STMicroelectronics · Comparators · SO-8

LM293DT from STMicroelectronics, in a SO-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 Out1 output Comparator 1 open-collector output. Requires an external pull-up to VCC+ (typ. 5.1 kΩ). Can sink up to ~16 mA (Vid=1 V, Vo=1.5 V).
2 In1- input Comparator 1 inverting input. Common-mode input range includes ground; input voltage must not go more negative than 0.3 V below VCC-.
3 In1+ input Comparator 1 non-inverting input. Common-mode input range includes ground; up to (VCC+)-1.5 V at 25 °C.
4 Vcc- power_in Negative supply / ground pin. Tie to GND for single-supply operation (2 V to 36 V), or to a negative rail (down to -18 V) for split-supply operation.
5 In2+ input Comparator 2 non-inverting input. Common-mode input range includes ground; up to (VCC+)-1.5 V at 25 °C.
6 In2- input Comparator 2 inverting input. Common-mode input range includes ground; input voltage must not go more negative than 0.3 V below VCC-.
7 Out2 output Comparator 2 open-collector output. Requires an external pull-up to VCC+ (typ. 5.1 kΩ). Sinks up to ~16 mA at Vo=1.5 V.
8 Vcc+ power_in Positive supply pin. Single-supply range 2 V to 36 V (referenced to VCC-), or up to +18 V in a split-supply configuration. Typ. supply current 0.45 mA at 5 V.
